No, it's ok to pursue that later if you feel such a connection (even covertly leaving your name and number on your tip like OP's now boyfriend could have done or on the receipt like OP ended up doing).

Later when you're literally not actively on a date with another person.

After you've given the other person the respect they deserve and either finished the date then turned them down for future dates, or ended the date then and there and escorted them home/to wherever you would have parted ways at the end of the date.

Basically, treating them in any other way than flirting with the waitress for an hour while on a date with them.

Literally having another date while treating your actual date like a fly on the wall.

What OP's now-BF did and what OP did are the actions of human garbage.

In that way, you could say they deserve each other.

But OP's now-BF's former girlfriend (third date is definitely approaching if not firmly in girlfriend territory) did NOT deserve how she was treated.

OP didn't respect the shit manager in the first place and so nothing he could have said then would make OP respect him enough to get him back to the job- OP's respect for the manager was at that time not an issue.

I knew this conservative conspiracy theory nutcase in one of my college classes who would argue with a political science professor during class all the time, and even spout crazy tin foil hat theories once in a while. The rest of the class didn't really mind because he was entertaining, but the professor despised him for wasting teaching time.

One day, the professor was talking about recent developments in genetic engineering and the moral ramifications of "designer babies" and future political issues that might come up from all of it. When suddenly:

Nutcase: "Gay babies!"

Professor: "...What?"

Nutcase: "Babies, that are gay!"

He then went on to explain how the entire field of genetic engineering was simply a plot by the extreme left liberals to genetically engineer the gay into babies. Turning the entire youth population gay in order to boost male perfume sales, and support the fashion and plaid industries.

The professor just stood there with his mouth open, not really sure what to say in response.

After a few minutes, someone in the back of the class replied, "Would it be that fucking terrible if all men stopped smelling like BO and dressed sharper?"

None of us could really argue that point. (I also later realized this meant that even in his crazed mind a conservative nutcase knows that being gay is a matter of birth and not a choice.)

No it can't mean that because the guy who ran away had come for revenge for Ivankov having killed his crew or his dad or something like that. Strong enough emotions to presumably make him run away. But the Newkamas didn't seem concerned, so presumably he's incapable of harming Iva or betraying their location now due to the hormone brainwashing.

And the guard who didn't ran away proceeded to betray his entire character as a prison guard of the toughest pirates protecring the innocent by aiding said pirates so that's also clear brainwashing.
